244 K. Martinez-Mayorga et al. As detailed in Chap. 1 of this book, similarity searching is at the core of chemoin- formatics, and multiple articles are published frequently on this topic. As expected, commercial software as well as programs developed by various research groups are available. For instance, ChemAxon, mentioned above, is a chemoinformatics plat- form and has a robust implementation of similarity searching methods. MOE and Schrödinger have also implemented structural similarity methods. Online resources are also available. For instance, MOLPRINT 2D and SEA (listed in Table 9.2) pro- vide for similarity searching, the former for ligands and the latter for proteins. Finally, an important commonly pursued goal is the prediction of bioactivity as well as ADME/tox properties. Physicochemical properties and bioactivities, and ADME/tox properties can be calculated through online services such as VCCLab, PASS, FAF-Drugs. Table 9.2 provides the corresponding websites, for more information. Being a major concern, a number of initiatives are dedicated to food safety is- sues. Some programs are maintained by, or in cooperation with, universities while others are consortia involving, in many cases, governments. Some of them are: the Centers for Disease Control [36], the Food Safety Research Consortium [37], ComBase [38], and Bits [39]. Developed and/or maintained by universities are: FareMicrobial [40], and the Center for Food Safety [41]. In addition, other online services are specifically focused on food information (food informatics). In these cases, the information contained is not necessarily di- rectly related to chemical structures, though it does illustrate the versatility of and need for using information technology to excel on tasks having a direct impact on health and well-being through food and nutrition. Vision Software assists the organization, storage and use of information, data and knowledge for food and nutrition-related problem solving and decision mak- ing. One direct application is in the area of diets for hospitals, hotels, etc. [42]. A related novel piece of work (albeit somewhat controversial) concerns so-called food pairing theory. The hypothesis is that a pair of ingredients which share many flavor compounds accompany each other better than those that do not, e.g., bacon and cheese, asparagus and butter, and chocolate and blue cheese. This food pairing concept is useful to understand and further develop culinary practice [43]. The Food & Biobased Research Company (Wageningen UR) has five major projects. One of them, called Food Informatics, focuses directly on food research. This project is conducted in cooperation with the Top Institute-Food & Nutrition (TIFN), Unilever Research, TNO Quality of Life research center, and Friesland Foods. Their focus is on the modeling of knowledge-intensive processes and the development of corresponding applications. Based on ontologies, Top et al. have focused on methods and tools for extracting knowledge in the food industry domain [44]. For example, using this approach, they have developed an on-line system for searching the properties and practical applications of five natural antimicrobial preservatives and their relationships to a large number of microbes and food types [44]. Another example consists of how these methods can help as decision support in the fruit and vegetable supply chain [45, 46].

9  Software and Online Resources: Perspectives and Potential Applications 245 Another online service is called Nutrition Informatics. Nutrition informatics is defined as “the effective retrieval, organization, storage, and optimum use of information, data, and knowledge for food and nutrition-related problem solving and decision making. Informatics is supported by the use of information standards, information processes, and information technology.” As part of the Academy of Nutrition and Dietetics, the Nutrition Informatics group provides a service to regis- tered members. It is the intersection of information, nutrition, and technology. The hugely data-rich food-related information includes food/nutrient analysis tables. This provides registered dietitians web-based tools, allowing them to use their knowledge and skills more efficiently in making dietary recommendations [47]. Another service that can be classified in this category is that provided by the O’Neill Institute for National & Global Health Law. It is a free online database of law, from around the world, relating to health and human rights. The database offers an interactive, searchable, and fully indexed website of case law, national constitu- tions, and international instruments [48]. 9.3 Perspectives and Potential Applications While the exploitation of chemical information in the food chemistry field is still emerging, this has already proven to constitute a useful approach, as illustrated through several examples described in the second section of this book and as also reported in the literature elsewhere. The use of similarity to compare and explore food-related databases, described in Chap. 1 and exemplified in Chap. 3 clearly demonstrate the applicability of these methods and alludes to exploring other applications; for example, expanding the studies to diseases, methodologies, and databases beyond those explored in Chap. 3. In addition, methods such as artificial neural networks proved useful when exploring the effects of foods on cancer cell growth, suppression activity, antivi- ral activity and antioxidant stress activity; this, of course, suggests exploring other diseases. The use of information technology in the food and beverage field is not limited to chemical structures. In fact, data mining is widely used to collect, organize, analyze, and archive diets in hospitals and restaurants, just as it is applied to chemical struc- tures in the area of chemical information. The theory behind the methods devised to perform these tasks is general and can be applied to datasets regardless of origin. Therefore, the software employed in drug discovery can readily be used or adapted to food chemical applications. In the same way that new concepts and methodologies are developed on an almost daily basis and reported in chemical information jour- nals, the food chemical information field can be expected to grow significantly during the coming decade. Taking into account the knowledge and applicability of chemical information devoted to drug discovery, and considering the inherent complexity of the food chemistry field, it is also expected that concepts now devel- oped in the food chemical information area will feed back into the drug discovery

246 K. Martinez-Mayorga et al. arena. This can be exemplified by the well-known complexity of odor perception, where multiple odor receptors are activated by multiple ligands, ultimately to pro- duce specific percepts. The multiple receptor/multiple ligand notion is central to the polypharmacology concept that is gaining attention nowadays. The idea of multiple target responses is neither new nor unexpected, however, only relatively recently is the paradigm change from single target to multitarget being recognized [49]. This interplay between drug discovery and food chemical information is not only promising but has also proven to be useful and may yet further expand our knowl- edge and boost our creativity in developing new methods to deal with complex multivariable systems. In the light of the discussion above, there is clearly a need for professionals with skills in information technology and a strong background in food chemistry. To fill this need, it will be necessary to explore the suitability of various chemoinformatic methods, selecting and developing the most useful candidates, and to design appro- priate programs and courses in universities. This has been the path of the chemical information field, but with emphasis in drug discovery. For example, chemoin- formatics courses leading to a Masters in Science have been implemented at the University of Sheffield, the University of Manchester and Indiana University. How fast we respond to this need will have an impact not only on the development of the field but also on how we take advantage of the emerging field of food informatics.
